Subject: [PATCH ethtool v3 3/4] ethtool: Rename QSFP-DD identifiers to use CMIS
Date: Tue, 8 Jun 2021 13:32:27 +0300 [thread overview]
Message-ID: <1623148348-2033898-4-git-send-email-moshe@nvidia.com> (raw)
In-Reply-To: <1623148348-2033898-1-git-send-email-moshe@nvidia.com>
From: Vladyslav Tarasiuk <vladyslavt@nvidia.com>
QSFP-DD and DSFP EEPROM layout complies to CMIS specification. As DSFP
support is added, there are currently two standards, which share the
same infrastructure. Rename QSFP_DD and qsfp_dd occurrences to use CMIS
or cmis respectively to make function names generic for any module
compliant to CMIS 4.0 or future CMIS versions.
